Title: Improvements in or relating to methods of and apparatus for forming members
Inventor: PHILLIPS CHRISTMAS
IPC: B21D7/022
Filed: 1962-05-04
Abstract: 969,380. Bending. REDMAN TOOLS Ltd Aug. 6, 1963 [May 4, 1962], No. 17319/62- Heading B3E. A method of forming elongated members comprises applying pressure on the elongated member by a pressure member, e.g. a pressure roller, to urge the elongated member towards a former and moving the former together with the elongated member in a substantially straight line past the pressure member. A member 15 to be shaped and which may be of channel section, is attached to a former 11. The former 11 is then moved forward along guides 16 so that a roll 12 may engage it. The roll 12 is urged towards the former 11 by an hydraulic ram 23 and the former 11 is moved past the roll 12 by the piston 18 of an hydraulic ram. The member 15 is thus forced against the former 11 and shaped. A member 15 so shaped may then be further shaped laterally by the use of a former 31 having cam tracks 32 thereon engaging fixed rollers 33 so that as the former 31 is moved longitudinally by its hydraulic ram it is also moved laterally by the rollers 33 and cam-tracks 32. When forming a hollow member an internal mandrel or spaced blocks may be used.

Title: Improvements in the Art of Producing Aluminium Carbide.
IPC: C01B31/30
Filed: 1917-11-26
Abstract: 112,929. Standard Oil Co., (Assignees of Barnett, M., and Burgess, L.). Jan. 26, 1917, [Convention date]. Aluminium carbide is made by passing current through a carbon or graphite core embedded in a mixture of two parts of alumina with one part of carbon, the mixture being heated to about 2000‹ C. Carbon may be in the form of petroleum coke. Residues from the distillation of petroleum with aluminium chloride may be treated with water, heated, mixed with additional alumina or carbon to rectify deficiency in either constituent, and employed as raw material. The materials are crushed to pass an eight-mesh screen. The mixture is fed into the furnace up to the level of electrodes 14, the solid or granular core 19<a> is placed in position, and charging is completed. Satisfactory working is indicated by evolution of carbon monoxide, and excessive heating by bright flames of burning aluminium. Unconverted material may be treated in subsequent operations.
Patent GB-1241881-A (GB)
Title: Apparatus for switching over a load from a power supply unit to a stand-by power supply or spare unit
Inventor: GERMANN F
IPC: H02J9/06
Filed: 1969-04-03
Abstract: 1,241,881. Stand-by supply systems. LICENTIA PATENT-VERWALTUNGS G.m.b.H. 3 April, 1969 [26 April, 1968], No. 17468/69. Heading H2H. A system for switching a load from a main supply to a stand-by supply without interruption includes a store which maintains the load energized during the switchover. In the case of an A.C. system, the two supplies are synchronized. As shown in the Figure, a first supply 1, which may be a thyristor inverter, energizes a load 3 by way of an energy store 4 and a switch 9 which may consist of a triac or an anti-parallel arrangement of thyristors, transistors or on/off thyristors. If the supply 1 should fail or become otherwise unsatisfactory, a monitoring device 6 begins to apply gating pulses to a second electronic switch 7, thus making a connection between the load 3 and the stand-by supply 2. After this connection has been made, and within the period during which the store 4 will still be supplying the load with a satisfactory signal, the device 6 acts to de-energize the switch 9 or to open a contact 8 so as to disconnect the first supply 1. A device 5 serves to maintain the supplies in synchronism and is monitored by a detector 10. If synchronism is lost whilst the load is supplied from the main supply 1, a contact 11 is opened to disconnect the standby source 2. If a fault now occurs in the main supply, a further contact 12 is closed after contact 8 has been opened so that the switch 7 is by-passed. The store 4 may include chokes and capacitors, or may be constituted by a dynamo-electric machine with a flywheel.

Patent GB-112430-A (GB)
Title: Improvements in Internal Combustion Engines.
IPC: F02B25/00
Filed: 1917-11-28
Abstract: 112,430. Chinese-American Co., (Assignees of Whaley, W. B. S.). Dec. 21, 1916, [Convention date] Regulating; valves.-In twostroke internal-combustion engines wording with gas fuel on the prolonged combustion system, a rich initial mixture is employed and a fresh charge of compressed air is supplied after combustion has commenced in order to complete the combustion and to stratify the burnt gases; the auxiliary charge may be employed for starting. Gas and air are supplied by ducts 68, 69 respectively, to a mixing- valve 70, Fig. 16, provided with perforations 71, 72 and a central partition and adjusted by a rod 73, the mixture passing to the pre-compression chamber 27 below the piston 43. At the bottom of its stroke, the piston uncovers the exhaust port 38 and admission port 36, at the same time allowing the passage of the mixture through its port 46 to ports 35 and a hand-operated throttlevalve 59 of the grid or other type, which controls the quantity of mixture admitted to the cylinder. Compressed air is pumped to a reservoir 86 from which it is supplied past a mechanically actuated valve 75, Fig. 3, to a chamber 87 connected by a spring-actuated poppetvalve 88 with the top 40 of the cylinder 25; the valve 75 is so operated as to open near the top and to close near the bottom of the down-stroke of the piston. When the piston has fallen about one-third of its stroke the cylinder pressure has fallen so low as to allow the valve 88 to open and admit air, which completes the combustion of the mixture during about the next third of a stroke. The residual gases are then stratified by the pressure of the incoming air so that when the valve 75 closes and the exhaust port 38 opens, the cylinder is efficiently cleared. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following matter. The invention may be applied to fourstroke-cycle engines. The initial charge may be a poor mixture, the supplementary charge consisting of gas. This subject-matter does not appear in the Specification as accepted.

The machine may include a pivoted, spring-biased yarn tensioning lever, and a device to stop the machine upon filament breakage. The table may support a circular array of pegs 1-60, Fig. 2A, the wound filament extending between circumferentially spaced pegs to form a voided, washer-like structure. Alternatively, a hexagonal peg array may be used, or two rectangular peg arrays, Fig. 6, the resulting voided structure having an offset aperture. Programmes of table rotation and peg extension are given, the programmes being repeated to build the required thickness of structure. The filaments, which may comprise yarn, braid or single or multiple strands, may be resinated before winding. The wound structure, e.g. a door or wall module for buildings, may comprise a central structure having large voids covered on one or both sides with a structure having small voids. A thick rim may be provided, with foam between the layers.

Title: Calcining lime-bearing sludges
IPC: C04B2/10
Filed: 1947-07-04
Abstract: <PICT:0643335/III/1> Lime-bearing sludges, e.g. from water-softening, paper mills, sugar factories are calcined by a fluidized technique in the presence of a material constituting an adhesive at the calcination temperature whereby nodules of lime are produced. Suitable adhesives are alkali metal hydroxides, carbonates or other salts, 1/2 to 2 per cent being employed.  Sludges which already contain more than sufficient alkali metal compound must be treated for the removal of the excess.  As shown, a sludge filter cake from filter 56, mixed with soda ash &c. at 65, is fed through a pug-mixer 55 to a cage mill 57.  The material dispersed therein is dried by the rising hot gases, and passes to cyclone 50, part of the material therefrom passing to the pug mixer 55, and the balance through conduit 58 and conveyer 61 to bed 42 where it is preheated to 1000 DEG  F. and fluidized by gases passing through apertured partition 40 from the calcination zone 13.  A variable amount of these gases is byepassed through pipe 77.  Coarse limestone may be added through pipe 62.  The preheated material passes down pipe 28 and is fed with fluidizing air or gas from pipe 26 to a manifold 18 and four pipes 17 terminating in ball check plates 16 to the calcination zone 13 wherein it is heated to 1850 DEG  F. by oil or gas fed in from pipes 32.  During calcination, because of the adhesive, the lime is formed into pellets which sink to a lower bed 71 wherein they are cooled, the air supplied through pipe 30, windbox 24 and apertured ball check plate 22 being insufficient to cause fluidization.  The material discharges through pipes 19.  Cooling air may, if desired, be passed in through tuyeres 70, which are used initially to preheat the charge to 1200-1400 DEG  F. by hot combustion gases.

Filed: 1942-12-15
Abstract: 688,824. Nuclear reactor. MINISTER OF SUPPLY. Dec. 8, 1943 [Dec. 15, 1942], No. 17850/42. Class 39(iv) The neutron-reproduction factor of a nuclear reactor is automatically maintained at unity. The reactor is combined with absorbers that are gradually adjusted to permit the factor to rise to a small margin above unity, within which margin the reactor stabilizes itself by small temperature effects. Cadmium or boron absorbers may be on the surface or inside the reactor and may form rods sliding within tubes. If the absorbers are hand-controlled, automatic safety devices override the hand controls. Small effects are produced as temperature rises to approach a safety limit by (a) decreased capture cross-section; (b) decreased density in a homogeneous reactor; or (c) partial discharge of the mass by expansion of a gas in a vessel within the reactor. The small margin allowed should be within the 1 or 2 per cent that can be accounted for by delayed neutron emission. The reaction factor of a two-medium reactor described in Specification 688,821 may be varied by adjusting the degree of filling of the inner core.

Abstract: 1,151,555. Filter networks. RANK ORGANISATION Ltd. 18 April, 1968 [19 April, 1967], No. 17999/67. Heading H3U. A sensor 2 receiving a composite signal containing higher and lower frequencies is coupled to a recorder 12 by a filtering arrangement which causes the recorder to receive only the higher frequency components and which does not introduce phase distortion. As shown, the composite signal passes to an amplifier 4 connected to a low-pass filter 8 designed to block the high frequency components and to introduce a phase shift in the low frequency components which is linear with frequency. The composite signal also is fed to a delay circuit 6 where a delay is introduced, without producing phase distortion, equal to that in the filter 8. The signals from filter 8 and delay circuit 6 are subtracted in differential circuit 10 whereby the high frequency components are fed to the recorder 12 without phase distortion. An application of the invention is where the sensor 2 comprises a stylus for assessing the surface finish of a machined workpiece and it is required to separate the high frequency components resulting from surface roughness from low frequency components resulting from other irregularities in the surface. As described with reference to Figs. 2-4 (not shown), the filter 8 comprises a transversal filter in series with a backing lowpass filter. The transversal filter provides an output equal to the inverse of the frequencies passed and thus the circuit 10 consists of a summing circuit. The delay circuit 6 may include magnetic tape recording and replay apparatus; alternatively digital storage techniques may be used (Fig. 5, not shown).
